Its Great! Except one tiny detail
Style: Wi-Fi, Size: 512GB, Color: Pink, Configuration: Without AppleCare+, Style: Wi-Fi, Size: 512GB, Color: Pink, Configuration: Without AppleCare+
Ipad works great, easy to set up and everything transferred from the cloud from a backup I had (thank god because my other ipad is completely dead). Everything is in order except they put the magnets in the wrong spot xD. It doesnt matter functionality wise and I feel its more hassle to exchange than its worth so I am going to keep the iPad. With the case its in it doesnt really matter because theres a spot already for the pen.
4/5 stars

Great iPad, so much faster and stable than our old one (5th generation). Totally worth the price to upgrade.

Quality and Functional
Color: Navy Blue, Color: Navy Blue
I was looking for a case that could rotate and includes a keyboard. I have the gen 5 Ipad Air and it fits just fine. The part that rotates is magnetic (pretty strong) so if i just want the part with the ipad, I can just take it off. Keyboard is magnetic and the touchpad is such a bonus. It was easy to connect and every key works (can also change light color). Im also really impressed with the quality of the case, its pretty thick and even the plastic is nice. The navy blue color is also super cute, wish they had a dark red color too.

ABSOLUTELY PERFECT - I LOVE THIS!!!
Color: Pink
I absolutely LOVE this case and the keyboard - it’s absolutely perfect in just about every way. If I had to get nit-picky and find something to give feedback on, I would say it is a bit heavy and it is a bit annoying that you have to move the keyboard forward when you want to use it and backward when you want to close up the case but I don’t care, I love it!
